We getting there but not quite there yet

Thanks vodacom for coming back to me regarding my query. But even though a consultant phone to find out what exactly the billing should be for the data package and that they will see how they going to refund me and come back to me nothing more happened. I got my invoice for this month and yes im now charged about R30 less than what it should be but my refund is most definitely not just R30 over the 2 months i have been over charged. Please could i be informed on how and if the refund has been incorporated into my monthly payment and will i be charged less now every month for a certain period of time and then go to the correct amount of R279 or how are things now calculated regarding my refund. It would be much appreciated as i would really like to have this all resolved.
